Science
Mechanism of Action
This extract functions as a robust antioxidant by broadly neutralizing various free radicals and defending against UVB-induced oxidative stress, attributed to its rich content of anthocyanins, flavonoids, caffeic acid, and quercetin derivatives. Its anti-inflammatory capabilities manifest through reducing irritation and redness, alongside inhibiting nitric oxide production. The ingredient also contributes to skin brightening by inhibiting tyrosinase activity, thereby reducing melanin synthesis and hyperpigmentation. As a humectant, it enhances skin hydration by attracting and retaining moisture. Furthermore, it offers anti-aging benefits by mitigating damage from advanced glycation end-products (AGEs) and supporting collagen and elastin integrity, ultimately strengthening the skin's protective barrier against external aggressors.

Key findings
- 01 Prunus lannesiana flower extract demonstrably reduced signs of irritation in skin exposed to strong detergents and other irritants.
- 02 Prunus lannesiana flower extract provided protection to skin cells against free radical damage when exposed to UVB light.
- 03 An in vivo study using a cream containing 3% Prunus yedoensis flower extract showed significant anti-inflammatory effects, marked by a reduction in visual scores and erythema values in an SLS irritant patch test.
- 04 Prunus yedoensis flower extract reduced nitric oxide (NO) production by 31.83% in an in vitro setting.
- 05 Prunus yedoensis flower extract effectively prevented cell viability loss and inhibited reactive oxygen species (ROS) levels in UVB-irradiated HaCaT cells across various concentrations.

Dusting Analysis
Clinical studies on related Prunus species indicate efficacy starting from concentrations as low as 0.5% (for antioxidant benefits) and up to 3% (for anti-inflammatory effects). Therefore, concentrations significantly below 0.5% may suggest the ingredient is included for 'dusting' rather than therapeutic effect.
The Formula
Formulation
Stability
The extract's beneficial phenolic and tannin compounds are prone to thermal degradation, necessitating storage at low temperatures (around 4 ± 2 °C). Elevated temperatures (70°C+) and higher pH levels can accelerate anthocyanin degradation and reduce polyphenol yield. Optimal stability for polyphenolic compounds is typically maintained within a pH range of 4-5. The extract should be stored in a cool, dry place, shielded from direct sunlight.
Safety
Safety Profile
Prunus Speciosa Flower Extract is generally considered safe for cosmetic use, with individual allergic reactions such as redness, itching, or rashes being rare. Its use is permitted under regulations like the European Cosmetics Regulation. While specific CIR or SCCS assessments for Prunus speciosa are not available, the FDA has evaluated a GRAS notice for Prunus serrulata flower extract (a related species) as a flavoring agent, suggesting a broader safety profile for cherry blossom extracts.
